Application filed. June 18.

To all whom it may concern:

3e it known that I, DALTON K. WILSON, a citizen of the United States of America, and a resident of Waterloo, Blackhawk County, Iowa, have invented certain new and useful improvements in Controlling Means for Cultivators, of which the following is a specification. v

My invention relates to improvements 1n controlling means for cultivators and the like, and the object of my improvement is to provide means for permittingchange of the direction of travel of the device with or without, operatively shifting the implements thereof, to thereby ensure complete manual control as desired of both simultaneously or in alternation.

This object I have accomplished by the means which are hereinafter fully described and claimed, and which are illustrated in the accompanying drawings, in which Fig. 1 is a side elevation of my improved cultivator, with parts removed or broken away, and Fig. 2 is a side elevation of such a cultivator with a modified form of implement controlling-means, parts also being removed or broken away, including the prime-motor and transmission mechanism. Fig. 3 is a top plan view of the cultivator, with parts removed. Fig. at is a rear elevation'thereof, and Fig. 5 is a front elevation thereof, with parts removed or broken away.

In'all said figures, similar numerals of reference denote co responding parts throughout the several views.

My improved cultivator is preferably of the riding type, propelled by a prime-motor 22 mounted on the frame 9 thereof, but in principle, my improved controlling-means for simultaneously or selectively operating the steering-wheels and the gangs may be applied to a machine of any other type, that is, propelled manually or by other power, and containing difierent working appliances or implements.

The numeral 13 denotesa pair of independently rotatable carrying wheels upon which is supported and mounted a rigid skeleton frame made up ofside-members 1 connected by cross-bars 2, 3 and at. The sidebars 1 have rearward extensions numbered 5, whose rear extremities are connected by a cross-bar 15 upon which a drivers seat 16 is From the frame depend rigid hangers 21, 55 and 7, which are Specification of Letters Patent.

connected at their lower ends'tothebars 20,

the latter underlying the bars 1 and having their rear ends raised a'ndsecured' to the rear ends of the bars 5. The stub-axles 8 of the carrying-wl'ieel's 18'have their inner ends fixed inboxings' (notshown) mounted in the, spaced'hangel's 7, the wheels being'rotatable on said fixed axles, and having mountedconfcentrically on their inner faces the sprocketrim's l7 driven by the sprocket-chains 35.

The prime-motor 22 is mounted on forwardly extended parallel longitudinal bars 9 of said frame, which are connected at their forward ends by a hollow rectangular casting 11, and are braced'b'y inclined bracebars. Other brace-bars 10 also are connected between the forward parts of the bars 9 and the lower parts of the hangers 55, whereby a rigid but light frame construction is afforded.

The forward part of the frame'is sup? ported upon the pair of dirigible steeringor caster-wheels 14. These are mounted on pintle-shafts or axles 18 whose ends are mounted in bearing-openings in the lower parts of spaced hangers 19. Between'the upper ends of these hangers 19 are fixed a hollow block 7 9 having alined openings in its upper and lower parts to receive the diminished ends of a fixed pintle-body' 78 whose upper end is secured in an openmg 1n a'block 80 secured upon the crossbar 12,

the latter being fixed across the two framemembers9. From the upper part of each pintle 7 8 projects downwardly and rear wardly an arcuate integral arm 76, having on its lower extremity a longitudinally-oriiiced body 77, in which is mounted the-forward end of anupwardly andinwardly inclined brace-rod 75, secured by an adjusting nut, and this rod 7 5 is alined with a radius of the wheel 14, thus giving increased support to same and to the pintle-block 78 which carries the other block 79. From the upper part of eachblock 79 projects rearwardly a short integral arm '81.

The numeral 82 denotes a pair of transversely-alined bars, whose outer ends are pivotally connected to the rear ends ofthe arms 81; On the inner ends of the bars 82 are fixed angle-plates 83, whose'upstanding parts are orificed' in line ,to receive the threaded ends of an adjusting-rod 84, se curedby adjusting-nuts.

The numeral 71 denotes a pair of longitudinally arranged tubular beams whose rear ends terminate in fixed risers 90 with handleloops 73, as shown in Fig. 1. To the forward extremities of the beams 71 are fixed outwardly-curved arms 89, whose outer ends are pivotally connected at 88 to the outer ends of the transversely alined bars or rockarms 86, which have their inner ends pivotally connected at 87 to the cross-bar 12. The arms 86 have integral rearwardlyextending arms or branches 85 which are pivotally connected to the inner ends of the bars 82. The radii from the pintles 87 to the last-mentioned adjacent pivotal connections are each equal in length to the length of each arm 81. The looped handles 73 of the controllerbeams 71 are positioned conveniently in front of the seat 16 for manual operation by the driver, who may shift these controllers longitudinally in order to simultaneously rock the wheels 14: laterally as desired to change the direction of movement of the machine.

A pair of gangs 60 having thereon stirrups ill and 92 respectively are positioned longitudinally below the main frame, and their forward extremities have an universal-joint connection with the supporting hangers 21 and 55, and bar 20. This universal-joint comprises a housing member fixed on the forward end of the gangs 60 carrying a pintle 58 Which has rearwardly-extending lugs 57 pivoted at 56 to said supporting elements, whereby the gangs may be swung laterally or up and down. in said gangs are mounted shanks 61 carrying shovels 62. I have shown in said-Figs. 1 and 2 two variations of swinging-connections between the gangs and the controllers 71. thereabove. These both come within the principle of my invention, which contemplates such a loose connection between said elements that the controllers may be operated in changing the directionof travel of the machine, or may be used to. simultaneously change such direction while otherwise shitting or moving the gangs.

In Fig. 1, a standard is swingingly erected upon the gangs and connected to the controller-beam 71 above by a loose or universal joint. This standard may, as in said figure shown, comprise spaced bars 6% which are passed down on opposite sides of the gangs and havetheir lower extremities con- .nected to a bearing-casting or block 6 1; by I means of a pintle-bolt 64 The upper ends of said bars are connected by a bolt, which in turn has a link-connection with the eye of an eye-bolt 643, the latter traversing the beam 71 andsecured thereto. I have supplied a yieldable resilient connection between. the main frame and the two-part or bar standard 64, which consists of a coiled tension spring 67 whose forward end is connected to a bar 68. This bar 68 has a threaded pin extension on its forward end which traverses an opening in a bowed bar 69 and is secured thereto by an adjusting-nut. This bowed bar is fixedly mounted on the hanger The rear end of said spring is connected to a short bar 66, whose rear end is pivoted on a cross-bolt of the standard-members 64, whereby the latter as also the gangs and. the controller above are elastically supported. The connections between the ends of the standard 64 and the controller and the gangs are such as to permit of swinging of the gangs laterally or up and down, and

in such a manner that the controller may be shifted to and fro longitudinally without relatively moving the gangs.

In said Fig. 2, a similar result is effected. The numeral 93 denotes a short verticallydisposed standard fixedly mounted on the gangs 60, and a like tension spring is connected to its upper end. To the rear of this standard, a standard 72 is swingingly erected on the gangs. This standard may be a tubular member 72 having a fork 72" at its lower end which encompasses the gangs and is pivotally connected to a bearingblock 72 on the gangs by means of a pivotbolt 72 The upper part of the standard 72 has a looped handle 73 projecting rearwardly, and the standard is connected to the rear extremity of the adjacent controllerbeam 71 by means of a freely linked connection 72 of the universal-joint type. This devieealso permits either separate use of the controller in changing the direction of the machine, or the simultaneous coactions of the dirigible steering-Wheels and the shifting as desired of the gangs. 2

The controlling of these actions selectively by the longitudinally movable controllers, is consonant to the usual method of control of such machines, whether power-propelled or animal-hauled, the operators movements being normally longitudinal, which does not either directly or indirectly cause sidewise shifting of the gangs when the controllers are employed only for changing the direction of travel. The operators attention is not disturbed, and the implements perform more perfect work.

Having described my invention, what I claim as new, and desire to secure by Let ters Patent, is: V

1.
